| 摘 要： | 研究滴灌施肥和沟灌施肥对保护地番茄产量、氮素吸收和土壤Nmin（硝态氮和铵态氮）残留的影响。试验结果表明，相同施肥水平下，滴灌施肥较传统的沟灌施肥可以提高番茄的产量，同时促进番茄地上部分对氮、磷、钾养分的吸收量，在0～40cm土层中滴灌施肥方式土壤Nmin残留量明显高于沟灌施肥土壤Nmin残留量（P〈0．05），说明滴灌施肥方式可以减少浅层土壤中的氮素淋失。

| Abstract: | The effects of drip fertigation and furrow irrigation with fertilization on protected tomato yield, nitrogen absorption and soil Nmin residue were studied in this paper. The results showed that under the same fertilization level, drip fertigation could increase tomato yield, and promote the absorption of nitrogen, phos- phorus and potassium by aboveground part of tomato. The residual Nmin in 0 - 40 cm soil layer under drip fertigation was significantly higher than that under furrow irrigation with fertilization, which indicated that drip fertigation could reduce the nitrogen leaching in shallow soil layer. |
